移动P2P流媒体中的数据调度算法

为了解决移动网络中分层流媒体的数据调度问题，提出了一种新的应用于移动网络P2P(Peer to Peer)流媒体的数据调度算法--二维数据调度算法。该算法将流媒体数据块分别使用二维坐标进行标注（块坐标和层坐标），数据调度过程中数据块的调度顺序由其二维坐标确定。仿真结果表明，二维数据调度算法能保证移动终端上的流媒体的顺畅播放；无用包率减小，使无线网络中带宽得到有效地利用；对层订阅抖动具有较好的抑制作用，确保流媒体质量稳定。

Data Scheduling Algorithm in Mobile P2P Streaming

In Mobile Network,a new data scheduling scheme named two-dimension data scheduling scheme was propsoed to be used in wireless mobile P2P(Peer-to-Peer) streaming to address the scheduling issue in layered streaming.In the scheme,each data in the streaming was marked with two-dimensional coordinates(blcok coordinate and layer coordinate),and the scheduling order of the data is determined by its two-dimensional coordinates.The main contribution of our scheme comes in three-fold: it can assure the fluency of ve...
